Definitions

  • this invention has as an object thereof the provision of novel apparatus for cutting lumber which has been found to result in appreciably more accurate cutting than is possible with most conventional forms of equipment.
  • a more specific object of the invention is to provide saw apparatus featuring what is referred to herein as disk bed for supporting the lumber as it is sawed, with plural raws of multiple disks in such bed, which a lumber piece is forced down against after properly being indexed, and before and during cutting. With this pressure applied, the edges of the disk slightly penetrate the wood on the underside of the lumber with the result that the lumber is caused to move over the disks with any tendency for the lumber to twist or turned during such travel reduced to a minimum.
  • the thickness of edge 32 is selected so that with moderate pressure exerted downwardly on lumber riding over a disk such will penetrate slightly the wood of the lower surface of the lumber without such penetration being such as to cause noticeable and permanent score lines along the lumber.
  • the compression index of the particular species of wood should be considered as well as the size of the lumber stock being processed (which through its weight alone will cause a certain downward force to be exerted on the underlying disk bed).
  • the usual soft wood such as conifers, as exemplified by Douglas fir, such has a hardness or compression index lying somewhere betwen 280 and 850.
  • the lumber on passing over the disks is indented by the disk peripheries, but the indentation is not so great as to excede what might be thought of as the elastic limit of the wood.
  • the lumber material passes over a disk it tends to be held from skewing or shifting sidewise, but the indentation of a disk is not such as to leave a permanent score line in the wood when such is inspected after having passed through the saw apparatus.
  • the action of a disk is shown in exaggerated form in FIG. 6.
